Automatic liquid measure



Jan. 8, 1935. EQJ. HANNA 1,986,811 I AUTOMATIC LIQUI-D MEASURE Filed June -2, 1934 Patented Jan. 8, I935 v UNITED STATES-PATENT OFFICE am-1:32:1 MEASURE The present invention relates to a liquid measure and more in particular to a novel attachment for a bottle or Other liquid container by which the dispensed liquid may be accurately and automatically measured without the danger of spilling.

.Among the objects of the present invention is the provision of a novel liquid measure and dispensing device whereby a predetermined and definite amount or quantity of liquid may be poured from a bottle or other container. A further object of theinvention is the pro.- vision of a novel liquid measure whereby a predetermined amount of liquid may be pouredwithout loss or danger of spilling.

Another object of the-present invention is the provision of a liquid measure and dispensing device whereby a definite and predetermined quantity of liquid may be safely poured in a minimum period of time- Such liquid may be poured and dispensed under the most t yi conditions as in the pouring thereof on a moving train, boat, bus, automobile, airplane, or whereverdifliculty is encountered in pouring a desired quantity of liquid.

A still further object is the provision of a novel attachment for a bottle or other container, in which the attachment forms a stopper or closure as well as a measure and dispensing device which accurately measures and dispenses apredetermined and desired amount of liquid.

Theinvention is admirably adapted and. has a wide spread application in the pouring and dis-. pensing of liquor for the purpose of making or drinks-and where an accurate and predetermined quantity of one or more given liquors and/or liquids is essentlalto the proper mixture or concoction. However, it is to be understood that the invention has a wider field 0! application and may be employed for the pouring of any liquid or fluid from a bottleor other container where an accurate quantity oLthe same is desired. I

Fm'ther objects are'to provide a construction oi. maximum simplicity, efliciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later laims.' 01. 221-98) prehends other details, arrangements of parts, features and constructions without departing from the spirit of the invention.

In the drawing:---

Fig. 1 is a fragmentary view, part in side elevation and. part in vertical cross section, of the novel measure mounted in a bottle or other container.

Fig. 2 is a view similar to Fig. 1, but with the bottle tilted and the measure in a position to v receive a predetermined quantity or level of liquid.

Fig. 3 is a plan view of the measure and taken on the line 3-3 of Fig. 2.

Fig.4 is a view in horizontal cross-section taken in a plane represented by the line 44 of Fig. 1.

Fig. 5 is a fragmentary view in perspective of the inner end or the shank or inlet for the measure. a

Figs. 6 and 7 are views part in side elevation and part in vertical cross-section of alternate formsoi the novel liquid measure.

Referring more particularly to the disclosure in Figs. 1 to 5, inclusive, the novel measure 1- is shown as an attachment for a bottle or other liquid container 2. The measuring device 1 comprises an open cup-shaped receptacle 3 of a predetermined size and desired shape and proand communicating at its one end with an opening or port 8 in a side wall or the receptacle, and its opposite. end 9 communicating with the inte-' 'rior of the bottle or other container. As shown in the drawing, the bent end of tube '1 is extended In Figs. 6 and 7 are shown alternate constructions, in which the receptacle 141s of the same shape, but the tube forming the air vent does not communicate with an opening in a side wall of the receptacle, but in Fig. 6 the one end of the tube 16 is positioned within the receptacle and opens upwardly, while in Fig. '1 the one end 17 or the tube 18 communicating with-thereceptacle opens downwardly. In each alternate form the opposite end 19 of the smaller tube is inclined similar to the form shown in Figs. 1 to 5,- inclusive.

In each form the opening of the air vent leading from the receptacle to the bottle or other container is placed at a level above that of the liquid inlet. Thus air flows through the smaller tube or air vent to the interior of the bottle; whereby to replace liquid poured or flowing therefrom,

. until such time as the liquid leveljin the receptacle rises to a height suflicient to cover the opening to the airvent to thereby prevent iurther flow of air to the interior pithe bottle. As soon asthe air stops flowing to displace the liquid content of the and-automatically determined, and after such predetermined amount is poured into or received in the receptacle such content may be poured without any danger of spilling.

Having thus disclosed the invention, I claim: 1. An automatic liquid measure comprising an open-mouthed receptacle for receiving and dispensing an accurately measured predetermined quantity of liquid, a hollow shank communicating at one end with said receptacle and at its other end with the interior of a bottle or other container, and an air vent leadingfrom said receptacle to the interior of the bottle or container and so located as to stop the flow of liquid through said shank when said measured quantity has been received in the receptacle, said vent being fixed in said shank withits inlet end ofiset with respect to the shank and terminating flush with a side wall of the receptacle whereby the interior of the receptacle is free from all obstructions to permit a thorough cleaning. of the interior of the receptacle.

.56 '2. An automatic liquid measure adapted to be mounted on a bottle or other container and comprising in combination an open receptacle, a shank connected to said receptacle and forming an inlet therefor, and an air vent in said shank .communicating with the receptacle and "interior of said container and rigidly connected to theshank' and to the side wall of the receptacle at the point where it enters said receptacle whereby to fixedly retain the vent and shanlr' in predetermined fixed position'so as to accurately measure the dispensed liquid.

3. An automatic liquid measure comprising an open-mouthed receptacle for receiving and dispensing liquid, a hollow member having its one end connected to'said receptacle and adapted to be mounted on a bottle or other container and communicating therewith, and a tube leading from said receptacle and adapted to communicate with the interior or the container and forming an air vent tor admitting air to said container, the inlet 01' said'tube extending toand terminating in a side wall'or the receptacle adjacent the opening to said membensaid receptacle having an unobstructed interiorto permit ready cleaning of the receptacle and said air vent accurately and automatically regulating the quantity of liquid flowing to said receptacle.

- 4. A sanitary liquid measure for automatically and accurately measuring and dispensing a predetermined quantity of liquid, comprising in combination a receptacle having a completely unobstructed interior and a discharge outlet of greater cross section than the remainder of the receptacle whereby to permit ready dispensing of the measured liquid, a hollow shank communicating with the interior of said receptacle and its other end adapted to be positioned in the outlet of a bottle or other container, and an air vent tube having its inlet terminating adjacent to and rigidly connectedwith a side wall of said receptacle and its outlet adapted to extend into the container, said tube being further mounted through a substantial part of its length on the interior of the shank whereby to rigidly retain said tube and prevent damage thereto in the and removal of the measure from the container. 5. An automatic measure adapted to be mount ed in the discharge end of a bottle or-other container for accurately measuring and dispensing a given quantity of a fluid, comprising a receptacle forreceiving and disp g saidfluid, a Shank on said member communicating at one end with said receptacle and at its other end with the interior of the container, an air vent disposed in said shank and communicating with the interior" of the receptacle and of the container, a. stopper encompassing said shank and adapted to form a seal'with the discharge end of said container, an abutment on said shank against which an end of said stopper seats, and projections on anendof said shank adapted to seat against the opposite end of said stopper for retaining it against longitudinal displacement.
